Description
fix ZEN-414
This disentangles the fetching of chart data from the chart. The reason behind this is that fetching chart data has some failure cases (e.g. a column for a slice filter does not exist anymore) that should not break charts altogether. It should still be possible to change the chart spec. Furthermore, this adds an error message if the chart data could not be loaded.
