Show and hide the graphs in a chart by clicks on a button

[Anonymous]

Hi,

I need a function, where can i show and hide the graphs in a chart by clicks on a button.

For example i make a field with two buttons.

1. "Button Count"

2. "Button Sum"

If i activate the button "Button Count" the blue line should showing in the chart.

If i activate the button "Button Sum" the red line should showing in the chart, too.

If i deactivate the button "Button Count" the blue line don´t should showing in the chart, but the red line (because "Button Sum" is always activated.

etc.

How can i do this?

Regards,

Fritz
