Color Ranges with SpotOn Vantage vCharts
Posted by Chris Ovens on Wed, Apr 28, 2010
Hello everyone,
The goal of this post is to get you familiar with Color Ranges. Color Ranges are simply an association between a range of values and a color. Many of our gauges look best when they include color ranges and you all deserve at least a insiders look at how to quickly configure them.
Lets get started and make a Vertical LED Gauge.
- Take the normal steps in Chart Studio (the Vertical LED Gauge is located in the Gauge Chart Group).
- In the Choose Data section pick the query and the measurement field.
- TIP ALERT: Now that we have the field selected and before we set up the color ranges, lets preview the chart. It is going to be black for now, but previewing gives some important information:
- Lets us now the value we are going to show
- Lets us see what range of values the chart defaults too.
- Now, armed with the knowledge gained from the preview, we can configure the Color Ranges by clicking on "Color Range Definitions".
- Now we can add colors and set their min/max values to fill up sections in the gauge. For example, The range of my data is 0-60M, so I am setting three ranges: Red with max value = 25000000, orange with max value = 45000000, and green with min value = 45000000.
Congratulations, your done!
Here is a look at my chart:
