Gauge control with two values (Silverlight)
While developing the dashboard to display several performance indexes, I bumped into the task of visualizing the pair of numbers on a single gauge. One number would show a person's performance metric, while the other one would display the person group's performance indicator to compare with. I couldn't find a ready control to use, so I decided to design my own.
I took the look idea from Fusion Charts flash controls (highly recommended), which I was using a couple of years ago:
I needed the same thing, but with two values displayed at the same time. Requirements are pretty simple:
- Three colored zones (low-red / average-yellow / high-green) with configurable thresholds
- Configurable min and max values
- One value marker on top of the gauge and another one on the bottom
- Bubble with exact value next to each marker
- All control properties are ready to be data-bound
- Flexible size
- No ticks needed Here is what I ended up with:
Quite minimalistic and sexy ;-) The control usage is self-explanatory:
<local:Gauge x:Name="Gauge" Value="71" SecondValue="84" RedThreshold="60" YellowThreshold="80" MinValue="0" MaxValue="100" Width="400" />
Source code has no rocket-science inside, so I won't post it here. You can download the Gauge control test application here.
