How to: Dynamically adjust how large data to show on scroll chart

[oburixus]

Hello,

 

 

 

I used amCharts for sometime, and couldn't find a must have feauture with fusioncharts, which i recently began to use.

 

 

 

Is it possible to let the user choose the data range to display? By means of expanding/shrinking the scroll bar with use of handles?

 

 

 

See amcharts for example: http://www.amcharts.com/stock/multiple-data-sets/

Hello oburixus,

The line-chart comparison is easily possible using FusionCharts.

Refer: http://www.fusioncharts.com/gallery/Category.asp?LineArea

Particularly, you may refer to http://www.fusioncharts.com/gallery/Chart.asp?msline_1 .

The radio-selection functionality under the "Compare to" section of the sample you provided can be easily implemented using JavaScript. We already have a similar example for the same, but it is done using Column Chart and can also be implemented using Line Charts as per your needs.

Refer: http://www.fusioncharts.com/Demos/JS/Index.html .

You may also download the same from http://www.fusioncharts.com/Downloads/Demos/FusionChartsJS.zip .

Now, the data quantity/range adjustment functionality using the handles (as per your screenshot,) is not available in FusionCharts at the moment. However, similar functionality can be emulated using JavaScript with the easy-to-use JavaScript integration of FusionCharts.

We can discuss upon further issues if you have any.

Thanks for the JS heads up.

 

 

 

But, when comparing, another issue arose.

 

 

 

The comparison should be done in %; to be logical, to show the change amount. So there will only be 1 Y axis, showing the % change. I am trying to figure out how to set it up from the settings, and appreciate a hand in here

Hello,

 

 

 

To show only one Y axis in percentage values, you need to enter the values in percentage.

 

 

 

I'm afraid, I could not fully understand your requirements. If you can elaborate more on this, I can surely help you out.

[oburixus]

What I was trying to say is, that FusionCharts will calculate the percentages automatically, hence eliminating time loss to calculate that percentage yourself.

 

 

 

But i guess this is not supported as of yet. So I ended up doing calculating the percentages myself, feeding the raw data.

[Guest Madhumita]

Hello,

You are right. As of now, FusionCharts can not convert values to percentage.

However, your suggestions are very important to us. We have made a note of the same.

Hi,

 

 

 

I am new to FusionCharts and came across this forum topic while researching a must have feature that I do not see how to accomplish in FusionCharts. That is the need to display a scrolling X and Y axis ranges with handles to adjust the range. Currently we have an application using a java applet from EasyCharts to accomplish this. Since I am already implementing the use of FusionCharts across many applications in my company I would naturally like to use FusionCharts in place of this old java applet.

 

 

 

As an example of what I am needing go to and check out the left/right and top/bottom range handles on both of the Y axis and the X axis.

 

 

 

I'm afraid that if I cannot accomplish this in FusionCharts it may result in a show stopper for me in expanding the use of FusionCharts.
