ThoughtSpot's charts can support many data values, and you can easily understand how much of the data your chart displays.

High cardinality charts

ThoughtSpot charts contain several new features. You are no longer limited to 1000 data points. When your chart has a very large number of data values, you see a horizontal scroll bar at the bottom. The new default maximum number of data points is 20,000. You can configure this maximum, up to 35,000. To configure the maximum number of data points on a chart, contact ThoughtSpot Support.

High cardinality chart with scroll bar

If you want to see the whole chart at one time, you can select the fit to screen option. To fit to screen, click the edit chart configuration icon, and select the Settings menu. Select fit to screen.

High cardinality chart example - fit to screen

When you fit to screen, you see the whole chart. You can easily return to the zoomed-in view, by unselecting the fit to screen option.

Note that when you enable fit to screen, the all labels option is grayed out. You cannot turn on all labels when you fit to screen, unless the visualization does not have enough data points to require a scroll bar, and thus defaults to fit to screen mode.

You can now have more than 40 legend items in your chart. You can slice with color using a column that has up to 250 values.

If you attempt to slice with color using a column that has more than 250 values, ThoughtSpot does not display the chart. You receive this error message, telling you to filter to reduce the number of values:

Filter to reduce number of values

ThoughtSpot also warns you if your search contains too many data points, so that you can filter your search.
