Simple Diagram - It is impossible to display values between 0 and 1

created 3 years ago

Hello support team,

Wants to display a Donat chart with percentage values. But I can't. If I take the percentage values and NumberFormat = 0.00%, the values are multiplied by 100. 10% = 1000%.

If I take the percentages and divide them by 100, the Donat chart doesn't show the values. The diagram remains empty. Only values > 0.5 are displayed. Values <= 0.5 are not displayed, will probably be rounded down to 0.

See sample program button "Draw Donat Value" and "Draw Donat Percent".

Kind regards Stefan from Vinschgau

    Hello Stefan,

    Thank you for testing the Preview version of our Chart Control. It seems that you are right, there is no way to show percent values in this case. We will try to find an appropriate solution for such scenarios in future builds.
