How to deal with charts flat lining due to huge range in data?

[nemesis256]

I need to make a chart with multiple lines on the same axis that will have a huge range. For example, one line will start at 10, go up to 50 over 30 points, the second may start at 30,000 and go up to 40,000 over 30 points as well. Because of huge range, and relatively small change in the data, the lines will apear flat.

 

Is there a way to make this prettier to show the growth? Can I maybe have the user hide one of the lines and have the chart Y axis regenerate (with setAdaptiveYMin turned on)? Or can I have the Y axis break up, so the range might be 0-50, ignore 50-30,000, then 30,000-40,000?

Hi,

 

If you have varying range of data on Y-axis, then you need to use logarithmic axis instead of linear axis. You can select any positive base (apart from 1) for your logarithmic scale and the chart gets plotted accordingly to the scale provided. Following are the two charts that support Logarithmic axis:

 

1. Log Line 2D chart - Similar to Multi-series Line 2D chart except that this chart uses Logarithmic axis. 

For information on this chart, please refer : http://docs.fusioncharts.com/powercharts/Contents/index.html?Log/Overview.html

 

2. Zoom Line chart -  It is meant for plotting large quantities of data , which if plotted on an ordinary line chart will produce indecipherable results. You can use this chart, if you have many datasets too along with them being in varying ranges.

For information on this chart, please refer :http://docs.fusioncharts.com/charts/contents/AttDesc/ZoomLine.html

 

Also, it is not possible to have the user hide one of the lines and have the chart Y axis regenerate or break up the range,as of now.

 

Hope this helps.
