Gant chart dynamic height

[StimulsoftUser]

We use a Gant chart. A single horizontal rectangle represents 2 time-related information and 1 category information. How to ensure automatic expansion of the chart vertically (with constant rectangle height) depending on the number of such rectangles.

Let's assume that we place a component on the page in the designer - a Gant chart with a height of 1/2 the height of the page. When generating a report, the chart receives data from the back-end (appropriate data source in the dictionary). If we get only 1 value from the backend, we will have 1 horizontal bar on the chart. If we get 5 values ​​from the backend, we will have 5 horizontal bars on the chart, but their height (thickness) will be smaller. In cases 1 and 2, the chart takes up 1/2 of the page. We want the height (thickness) of the horizontal bar to remain the same and the height of the chart to change, i.e. so that the chart can "grow" vertically, just like a table.

Hello,

As a way, you can check count data and set the Height property of the Chart component in events.

Thank you.

Hello Lech,

Can placing a chart on a component that can expand vertically cause the chart to also grow in height ?

For example, onInteraction event:

No. The chart component has static height and width properties.

Thank you.
