You need to get json, call point.update and chart will be redrawn.

my problem I have an highcharts graph type column with drilldown values and I want to add dynamically another series of data with drilldown values
can anyone help me with this problem ??
Just Make data in your back end language and convert into JSON then update chart either by using ajax or on page load.
I am trying to replicate the highcharts drilldown chart, using multiple series in the data and drilldown data, and external source csv/json data files
I can easily recreate the drilldown using the examples from highcharts
I can create a column chart using csv as source for data
I have been able to create a multiseries to multiseries drilldown using this example ttp://jsfiddle.net/7xEhW/496/
What I am struggling with now is how to load the data from csv in a format that is accepted into the drilldown (multiseries)
This is my code for the parsed
http://jsfiddle.net/9gshkdaj/
I can make it work if I insert static data into the drilldown, but any help on how to load this via a csv would be appreciated (I have control over csv format).
My other idea was to use the data.parsed function to modify the data, but I have no idea where to start (although I know it should be possible, as this example is actually loaded from a tsv) http://www.highcharts.com/news/125-new-features-drilldown-and-no-data
Thank you

I am trying to create a radar chart dynamically based on the number of records coming from the server as json data.
For example: my json has 1000 records and I try to create radar chart to show the data but my html page getting hanged.
I tried it and it is working up to 50 charts.
This can't be fixed.
Every single chart you render requires a significant portion of processing time to be built. The more charts you want to render, the more processing time it will take. There's nothing you can do about that.
Either try to condense your data into (significantly) fewer charts, or render an individual chart when a row is selected.
Or, (tell your clients to) get a beast of a machine.
I have a EXCEL file containing multiple Tables and Charts.
I want to create a web page to display a particular Table and a Chart. I used java script to display the table.
But cant find a way to display the CHART. By chart i mean it contains a pie graph or bar graph.
Is it possible to display using java script? Or do i have to use JSP/something else?
Take a look at Google Chart Tools. Here is an example with javascript source code. If you are building the table on the server side, you may instead want to pass the data down JSON encoded and then build both the table and chart at the same time without having to pass the data twice.
An easier way would be to use a free tool like oomfo, which is a PowerPoint plugin to create charts. It lets you pull data from excel, create charts and then export the entire slide as HTML - the charts are in Flash and JavaScript (fallback). Just add a line of code in the output web page to render JavaScript charts only.
I am using jqPlot to show candlestick chart and the data is from XML.
I retrieve data from XML and put it into an array and then jqPlot creates a candlestick chart from that.
But the XML file contains lots of data so in the chart values are overlapping (with fixed width).
Is it possible to make a graph of lets say 10% of data and place a scrollbar and on every tick of scrollbar we rebuild graph with next data or there already exists such functionality of scrolling of graph/chart in jqPlot.
Please help me to resolve this.
Perhaps you can try Jonathan Cook's jqplot.annotatedTimeline.js available from the following URL:
https://bitbucket.org/j5bot/jqplot/downloads
You can see its features in action from:

Although I haven't tried this plugin yet it looks very good!
Its better to load XML at once, but not give the data at once to that jqPlot chart. Just make sure you are passing part of the data to jqPlot. Once you assign data to chart then go for the scrolling of data using jQuery or something like scroller code.
Whenever you scroll on this try to refresh or regenrate the chart by only the selected data.
