# Troubleshooting dashboards If a dashboard doesn't behave as you expect, find the symptom below. Each fix says who can make it: - **You**: anyone viewing the dashboard - **Editor**: someone who can edit the dashboard - **Admin**: someone with access to [**Application Settings**]() ## A filter doesn't change a tile Several filters can apply to a tile at once, and some take priority over others. If a filter doesn't change a tile, work through these checks in order: 1. **See what reaches the tile.** Select **Underlying Filter** on the tile's option menu. It lists every filter that applies to the tile, written out for the table the tile counts through. 2. **Look for a tile filter.** A blue dot on the tile's option menu shows an active [tile filter](), which takes precedence over any conflicting user filters. Only an editor can change it. 3. **Check for Exclude User Filters.** If an editor has turned on [**Exclude User Filters**](), the tile ignores user filters. 4. **Check whether it's a Pareto tile.** A Pareto tile [isn't affected by user filters from other tiles](). 5. **Check the table the tile counts through.** A filter on another table reaches the tile through the tile's [resolve table](), which can change what the filter selects. For the full rules, see [How filters combine](). ## Other filter problems These problems are about adding, applying, or changing filters. | Symptom | Cause | Fix | | --- | --- | --- | | Selecting categories doesn't update the dashboard straight away | [**Auto Filter**]() is turned off | **You**: build up your filter from several tiles, then apply it. **Admin**: turn on **Auto Filter** | | A tile shows `This tile is not selectable` | **Prevent Category Selection** is turned on for the tile | **Editor**: turn off [**Prevent Category Selection**]() | | You can't add user filters | [**Allow Filter By Dimension**]() is turned off | **Admin**: turn on **Allow Filter By Dimension** | | You can't add a search filter | You can't edit the dashboard, or **Dashboard Search Filters** is turned off | **Editor**: [share the dashboard]() with you with **Edit** permission. **Admin**: turn on [**Dashboard Search Filters**]() | | You can't edit a filter from a Venn tile | Venn filters can't be edited | **You**: delete the filter, then [select the subsets again]() | ## Tile problems These problems are about what a tile shows, and setting one up. | Symptom | Cause | Fix | | --- | --- | --- | | A tile shows more categories than expected | The tile counts through a higher table than its own, such as **People** for a chart of bookings. A filter then selects people, and the tile shows everything they have | **Editor**: check the tile's [**Select Via**]() setting | | The tile editor shows `Chart requires 2 dimensions.` | The chart doesn't have the dimensions or measures its type needs | **Editor**: [add them](). Most multi dimension charts need two dimensions and one measure, and combo charts need two measures | | **Type** and **Limit** are greyed out under **Category Limit** | The editor hasn't let viewers change the limit | **Editor**: turn on [**Allow the user to adjust this limit**]() | | The **Behaviours** tab is missing when you choose a dimension, measure, or filter | The table has no child transaction table, which behaviours need | Ask your system administrator. Behaviours need a [parent-child relationship]() between tables | | A calculated measure doesn't match FastStats | FastStats rounds during the calculation, but Orbit calculates to a higher precision | Nothing: small differences are expected. See [Calculated measures]() | ## Export and file problems These problems are about exporting a dashboard or a tile, and uploading files. | Symptom | Cause | Fix | | --- | --- | --- | | Images are missing from a PDF export | The images are hosted on an external domain whose server doesn't send permissive cross-origin HTTP headers | Check whether the server hosting the images allows cross-origin requests. See [Export a dashboard as PDF]() | | You can export a data grid tile in only one format, or not at all | **Restrict Export** is turned on for the tile | **Editor**: change or turn off [**Restrict Export**]() | | You can't choose **Permanent** for a URN file | All URN files in user filters are [set to be temporary]() | **Admin**: turn off **Force URN filter files to be stored temporarily** | ## Limits These aren't faults. Orbit works this way. | You can't | Because | | --- | --- | | Add a second Pareto tile to a dashboard | A dashboard can have only one [Pareto tile]() | | Drill down on a profile tile | [Profile tiles]() don't support drilldowns | | Compare analysis groups side by side on one dashboard | All the profile tiles on a dashboard share the same [analysis filter]() | | Use a behaviour as a measure on a Venn tile | On a [Venn tile](), behaviours can only define sets |
