I was looking for a chart library for use in the upcoming web application, but I have two requirements that turned me off:
- Ability to save the graph as an image.
- Show error bars at the points of line charts, as well as histograms.
I found solutions for # 1 using flash cards or the Google Chart API. However, requirement No. 2 completely stopped me in my tracks, it seems that all existing frameworks completely exclude this functionality.
I have already tried many libraries, including:
- Google Chart Tools
- It looks like they have the ability to place markers on points using the Chart API. This is only related to static images. No interactivity. In addition, the error marker marker can only be drawn between two series, and not stretched in any direction along the Y axis from one data point.
- Highcharts
- Great javascript graphic charts. As far as I can tell about the lack of error bars.
- amCharts
- I thought I found my solution here , but in fact it’s just a hacked bubble chart, where the bubbles look like error bars, and it appears that there is no functionality for drawing error scales on the histogram.
