Hi, In the latest release of PowerBI report server, we are picking up issues whereby chart visualizations are not returning data on shell dimemnsions that contain MDX calculations. This issue does not occur in older versions. I have pulled out the issue from the trace file; DataMashup.Trace Critical: 24579 : {"Start":"2017-11-07T10:27:45.1550000Z","Action":"PBI.Visual.Exception","Message":"{\"visualType\":\"clusteredColumnChart\",\"isCustom\":\"false\",\"apiVersion\":\"\",\"instanceId\":\"af4dba33-d083-0a1d-e8f2-cf40698b8a67\",\"source\":\"\",\"lineNumber\":\"\",\"columnNumber\":\"\",\"stack\":\"TypeError: format.split is not a function\\n at getComponents (ms-pbi://pbi.microsoft.com/minerva/scripts/visuals.js:16108:46)\\n at Object.getCustomFormatMetadata (ms-pbi://pbi.microsoft.com/minerva/scripts/visuals.js:16296:36)\\n at getMinTickValueInterval (ms-pbi://pbi.microsoft.com/minerva/scripts/visuals.js:30482:58)\\n at Object.createAxis (ms-pbi://pbi.microsoft.com/minerva/scripts/visuals.js:30304:940)\\n at ClusteredColumnChartStrategy.setYScale (ms-pbi://pbi.microsoft.com/minerva/scripts/cartesianVisuals.js:2454:57)\\n at ColumnChart.calculateAxesProperties (ms-pbi://pbi.microsoft.com/minerva/scripts/cartesianVisuals.js:2109:61)\\n at CartesianAxes.calculateAxes (ms-pbi://pbi.microsoft.com/minerva/scripts/visuals.js:44271:135)\\n at CartesianAxes.negotiateAxes (ms-pbi://pbi.microsoft.com/minerva/scripts/visuals.js:44382:32)\\n at CartesianChart.renderCartesianChart (ms-pbi://pbi.microsoft.com/minerva/scripts/cartesianVisuals.js:862:44)\\n at CartesianChart.render (ms-pbi://pbi.microsoft.com/minerva/scripts/cartesianVisuals.js:842:26)\",\"message\":\"format.split is not a function\",\"sessionId\":\"1a4a4068-d44e-42f0-978f-16d76036b808\",\"deviceId\":\"79ae87ee\",\"userId\":\"f8766298-a3b4-4a0a-8b5d-b362f7363f3c\",\"isInternal\":\"False\",\"authenticatedUserId\":\"83335a1c-1aa6-4f17-987c-5a3b30e82cd3\"}","ProductVersion":"2.51.4885.1041 (PBIDesktop)","ActivityId":"66c314e7-ed41-1a32-9e2f-d471e3f40093","Process":"PBIDesktop","Pid":12988,"Tid":9,"Duration":"00:00:04.4008741"} Thanks, Dillon
