23. Report and Dashboard Design Principles
23.6 Accessibility
Aata he bagha: accessible reports can be used by people with visual or motor impairments, and are simply clearer for everyone.
| Practice | How in Power BI |
|---|---|
| Alt text for visuals | Format › General › Alt text (can also use a measure for dynamic alt text) |
| Tab order for keyboard users | View › Selection › Tab order – arrange logical order; hide decorative shapes from tab order |
| Do not rely on colour alone | Add data labels, markers with different shapes, icons or text |
| Contrast | Dark text on light background (or vice versa); avoid light grey text |
| Readable font sizes | Avoid very small text; titles and labels large enough to read on a projector |
| Clear titles and labels | Every visual should be understandable on its own |
| Built-in accessible themes | Some built-in themes are designed with accessibility in mind (look for high-contrast/colour-blind friendly options) |
| Keyboard shortcuts | Users can press Alt + Shift + F11 to show a visual's data as a table |
The 5-second test
Show your report page to someone for five seconds. If they cannot tell you the main message, simplify the page.
Ravindra Bagale's Tip
Friends, many students rely on colour alone (red/green) to show good or bad, which colour-blind users can't see. Add icons, labels or text as well, check contrast, set alt text on visuals and set a sensible tab order in the Selection pane. Don't make this mistake!
Ravindra Bagale's Tip – मराठी
मित्रांनो, बरेच students चांगलं किंवा वाईट दाखवण्यासाठी फक्त रंगावर (लाल/हिरवा) अवलंबून राहतात, जे colour-blind users ना दिसत नाही. सोबत icons, labels किंवा text पण जोडा, contrast तपासा, visuals वर alt text set करा आणि Selection pane मध्ये योग्य tab order set करा. ही चूक करू नका!
Ravindra Bagale's Tip – हिंदी
दोस्तों, बहुत से students अच्छा या बुरा दिखाने के लिए सिर्फ़ रंग (लाल/हरा) पर निर्भर रहते हैं, जो colour-blind users नहीं देख पाते. साथ में icons, labels या text भी जोड़ो, contrast check करो, visuals पर alt text set करो और Selection pane में सही tab order set करो. यह गलती मत करना!
