Clarifications on Charts::Graph component

Question

I have implemented line a chart using Charts::Graph component by adding the coordinates. It is working fine. The Dot points are correctly placed, and line is also plotted correctly. There is another requirement on my project, that is adding touch events on the dot point. when pressing on a dot point, it should display a label which show the values of that dot point. We can't do any modifications inside the Charts::Graph. How can I implement?

Hello Tharanya,

the Charts::Graph component is deprecated and the unit Charts was removed since version 11 of Embedded Wizard Studio. Let me recommend to work with the Line Chart Template instead. The example ChartsDemo is also based on this template.

To answer your question: You can place a Simple Touch Handler over your chart and evaluate the touch position - then your application can react accordingly.

Best regards,

Manfred.
