Intermittent "The Selections generated no data for this chart " after app refresh. Anyone seen it

Hello community,

We are seeing a very frustrating intermittent issue with one of our dashboards. After an app reloads, at times we encounter the issue above with some of the visualizations.

Some app details:

We have February 2018 p2 version.

The same master measure is used in multiple visualizations. These measures do contain

While the issue is not exclusive to charts using alternate dimensions, we have seen it occur on those much more frequently than other visualizations.

There is some set analysis being used in the measures.

The sheet where we see the issue more has around four line charts, six kpi's and a straight table.

What we have observed:

We have ensured that there are no selections that could be affecting the rendering of the charts

The same measure will behave differently on the same sheet. On one chart it will render the message above and in the other the chart is present normally.

If I refresh the page, the visualization returns to form and I can see the chart. The same is true if i make a filter selection ( even if i simply select the filter and not accept the filter selection)

There are no console errors visible if we open Web develoment tools (F12 in chrome)

There are no logs pertaining to issues

This is a per user issue. Two users looking at the same sheet will see different behavior on the same chart.

Has anyone encountered an issue like the above?

Btw, we actually moved from November 2017 to February 2018 to try and see if the issue went away but to no avail.

Browser difference? I've seen where when the sheet is complex (Best practice is 5 or fewer visualizations) and network and PC loads come into play as the layout/rendering is client side, that sometimes it just stops and doesn't resize, like the UI missed a paint request because it was too busy.
The actions you describe trigger a new paint request and "fix" it.
Short answer, simplify the sheet if you can; in Feb 2019 switch to multi-KPI widget - it allows more KPIs in the same space as well
