Perhaps, the charts you mentioned are affected by the selections you make. If the chart has no data for the selected values, it will display nothing.
If the charts are displaying data when you click on the corners, it could be because clicking on the chart is resetting selections.
If its just read-only charts, you can make the expressions in charts independent of selections whereever possible. If not, you can try sharing a sample of the QVW so that community experts can get a better insight.
Is that what you are looking for?
The only time I've seen this is when conditional-show has been enabled in the Layout tab of the chart, and then the charts are placed within a container. As a rule, once a chart is in a container, you should not have conditional-show enabled in the chart, but rather only on the container level itself. Try checking that.
