Time-Series¶
In this section, we’ll go over time-series charts and how to explore them.
Examples of Time-Series Charts
Watch this short video about Newton Curve Plotting to gain a general understanding of the application:
Curve Respones¶
For scientific datasets, time-series curves can be plotted and viewed easily by dragging-and-dropping responses.
This Barrier Crossmember dataset contains columns of curves with one column denoting time.
Figure 1: Barrier Crossmember Dataset
We’ll drag the curve columns into a new page to plot the curve quickly. We can drag other responses onto of the plotted curve to replace the curve it or choose to overlay as many other responses as we like for easy comparisons.
Here is the curve plot with overlaid time-series curve responses.
Figure 2: Barrier Crossmember Curve Overlay
The curve responses on the left side in Simlytiks now have default Color By to be name column and response can be enlarged and viewed.
:sup:`Color By as Name `
Sidebar responses list in Simlytiks is now sortable and any changes made in this list will be saved to the schema
Newton Visualizer¶
Newton Visualizer, also referred to as curve plotting and curve viewer, is Simlytiks’ main time-series chart. It can support up to 100 curves and millions of points in one plot. Newton is highly interactive and customizable; some useful features include zooming, scrolling, dragging, highlighting and filtering. It also integrates with other applications on d3VIEW aside from Simlytiks.
We’ll be using the Occupant Belted sample scientific dataset which has curve responses with time as the x coordinate to help explain Newton.
Figure 3: Occupant Belted Dataset
Simply drag-and-drop a curve response into a new page section or choose curve plot in the visualization menu and input data for the plot.
Line Dash By¶
New as of September, 2022, we can add a line dash property based on data. In this example, we’ve chosen name as our line dash condition which renders each curve a different dashed line type based on the simulation name.
Figure 4: Line Dash By
Newton Tools¶
The following image gives an overview of the chart and maps out all its tools.
Figure 5: Newton Tool Bars
- Curve Legends: Shows names of all curves on the plot
- Right-Click Menu: Access these curve plotting options by right-clicking
- Top Right-Side Toolbar: Options include (from top to bottom) Chart Type, Zoom, Highlight, Drag, Add Text, Add Arrows, Measurement Tool, Free-form Datum Line
- Bottom Right-Side Toolbar: Options include (from top to bottom) Reset Options, Save Settings, Keyboard Shortcuts, Copy Chart, Import Curve(s), Export Options
Updated August 4, 2022, the right-menu click menu options are now grouped for a more organized experience:
Datum Lines¶
Create datum lines to better understand the curves by clicking on the line icon in the right-side toolbar or choosing the datum line option under the right-click menu. The toolbar option is free-from while the right-click option is axis based.
Datum values containers have Transparent background when y values are enabled in Datum lines.
A datum line in Newton visualization now shows an option called ‘Label Orientation’ which will allow the datum label to be oriented horizontally at the center of the datum line.
Datum lines in Newton having type as X or Y , will show an option to display the axis value within the label.
We can add custom Datum lines to Newton visualization in Simlytiks. This option is now available in the Misc tab in the visualization.
Datum lines now have a new option for Label Font Size in settings
Datum lines Label
New customization options are available for ‘Datum line By’ option in Newton visualization.
Added support for adding datum lines in Newton on the Y2 (secondary) or Y3 (tertiary axis). This option will be applicable only when there are curves on these respective axes.
Datum lines for Y1 and Y2
Datum lines in Curve visualization has additional type dropdown which will now display axis names instead of just X, Y, Y2 etc.
Annotations¶
We can add annotations by adding text and arrows to our plot. Start by clicking on the A icon to add text. Then click on the arrow icon to add an arrow. Watch the following video to see how it’s done.
Highlighting & Filtering¶
We can highlight curves to filter them in out of the plot. Click on the brush icon and click and drag to select curves. Then, click on the orange filter icon to remove or keep the selected curves. Watch the following video to see how it’s done.
Measurement¶
To measure curves, click on the ruler icon and then click two points sequentially to measure. Watch the following video to see how it’s done.
Curve Dragging¶
Drag curves around the chart to compare with other curves by choosing the crossing arrows icon in the right-side toolbar. We can choose the drag the curve freely, vertically or horizontally.
Customizing¶
Customize curves under the 3 dots in the right-side toolbar.
Figure 6: Newton Chart Types
Here, we can change font sizes, choose a different position for our legends, and make other modifications.
Reset changes anytime by using the reset options (circular arrows icon) in the toolbar.
Figure 7: Reset Options
Curving Brushing¶
When using the highlighter tool, right click on the chart to keep, exclude or remove the brushed curves.

Event Mapping¶
Newton has a feature that allows you to map and detect events of curves. Watch the following video to see how its works:
Sync¶
Click on the sync option at the top of a Newton page to sync the current page’s visualization together.
Figure 9: Newton Sync
Progressive Rendering¶
Progressive view for complex curves computes the top 5000 points along with not missing out of min, max, 0, and important drops in the curve. Since Newton syncs with other applications, this applies to any other curve viewing throughout the platform aside from just Simlytiks.
Figure 10: Progressive Rendering
Axis Ticks¶
Edit the axis ticks for both x and y axes by hovering over until the ticks are highlighted in gray and then clicking to pull up the edit options. Here, you can edit aspects such as the scale, unit and font size. Check out the following video to see how it’s done:
Editing Legends¶
In Newton Curve Manager, we can edit and use our legends to alter our chart. Hover over a legend name and click the pencil icon to edit it. The 3 dots on hover allows us to alter the particular record such as hiding it from the plot. We can also right-click on a record to see more visibility options such as hiding the record or deleting the curve all-together from the plot. Watch the following video to see how it’s done
Merged Show & Hide option available in the Legends right click for Curve Visualization in Simlytiks.
Transformations¶
We can explore our curves deeper by mathematically transforming them under the Advanced Settings menu (3 dots). Choose from a long list of transformations to apply. Watch the following video to see how its works:
In Newton, the ‘Transformations’ while operating curves are now called ‘Functions’
Transformations while operating curves are now called Functions
Keyboard Shortcuts¶
Newton has some keyboard shortcuts to perform basic actions more quickly instead of clicking them on the toolbar. Click on the keyboard icon on the bottom tool bar to see all the available hot keys. Watch the following video to see how:
Background Image¶
For Newton curves, we can add a Background Image , edit background Image and remove Background Image accordingly.
ShapeBy¶
Newton visualization can now show the first and the last points in different shapes. This new option to show first and last point is available in the appearance tab of new visualization.
Newton Chart Types¶
Under the eye icon in the right-side toolbar, we can change the chart type of our time-series plot. Aside from the main plot type, there are 10 other ways to view our curves. Let’s review a few of them.
Figure 11: Newton Chart Types
Watch the following video for a preview of some of the chart types.
Newton visualization has a new chart type to convert to Heatmap and also provides several options for bin size, color scheme to be chosen for the rendered heatmap.
Heatmap in Newton now supports new options to specify number of columns to use in the Appearance tab.
Number of columns to use
Heatmap in Newton now supports coloring the cells based on other curves when the option to color based on difference with other curves

Fit entire heatmap within container
Scatter Band¶
The Scatter Band chart type shows the band area of the curves along with the average curve of all (shown as the dashed line).
Figure 12: Scatter Band
Histogram¶
The Histogram chart type shows a distribution of data for each curve and how it relates to the others.
Curve Difference¶
The Curve Difference chart type takes the y current and subtracts the y previous to see where incremental variations are within each curve.
Figure 13: Curve Difference
Time-Series Summary Table¶
The Time-Series Summary Table chart type resents scientific data in the table cells including curves and histograms, as we see these respected columns.
Curve legends¶
Prefixes and suffixes can be added to legends in curve newton to make them more meaningful. Click on the ellipses for the legends, select either the prefix or suffix, then enter the text, and implement it.
Figure 14: Prefix and Suffix for legends
Existing legends in curve plots can be replaced with the desired text. Click on the ellipses and select “Search and Replace”, enter existing text and then desired text, and implement changes.
Figure 15: Search and Replace Legends
Legends in a curve plot can be replaced with images if the dataset has images in it as well; images will show up in the tooltip when hovered over the curve plots.
Figure 16: Replace legends with Images
Legends in a curve plot can be hidden and restored by clicking on the legend lines.
