I have created an Analytical App which is supposed to be used on the smartphone. A button in this app opens a popup that shows a chart. When the user taps on the chart, he has the possibility to maximize the chart.
Unfortunately, the popup does not close itself after maximizing. By clicking on a "close" button, the popup can be closed. When opened again, the chart is no longer displayed and the app freezes.
How can I disable the maximizing function of the chart in the popup?
Can anyone help me?
