Bug description

If I used a mixed chart with query A and B, the "Truncate Metric" checkbox is not working.

I activated both, but the metric is still shown on all data lines.

If I used area chart e.g., the checkbox works as intended and hides the metric in front of the data linen description in the tooltips and in the legend.
