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.

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 want to create this CHART, but i don't know how to start with that.. Because i cant found similar chart and i can't find any way how to create this one..
This graph i create just with CSS it's enough for now, but later i wanna receive a live data into chart so via CSS it's impossible and the chart is not responsive..
So any advice how to create this chart ?
Using jQuery or another one ?
I've searched around and not finding a proper solution/explanation on how to get this right. Essentially what I'm trying to plot would resemble something of the following:
| #
|# #
|## ##
|______
fb tw
So essentially two categories, facebook (fb) and twitter (tw). Each category needs two bars for previous month and current month (they are counts). The data is retrieved from server side data.
What I need to know is how to get this chart to work using flot? Fiddle of what I have so far here: http://jsfiddle.net/thorne51/ExUH7/1/
I've tried using the orderBars plugin (as is apparent with the order property in the bars objects) with no success, not that I'm exactly sure what this does. Still very new to flot.
Edit
If anyone knows where decent documentation on flot and its plugins exist, or a tutorial, please share :)
You didn't have the Flot Orderbars plugin included in your fiddle. I included it and updated the fiddle: http://jsfiddle.net/ExUH7/4/
I would suggest you think about changing either the x-axis categories or the labels of your data, having them both be 'facebook' and 'twitter' leads to a confusing graph.
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'm creating a page where javascript creates random numbers and then draws a Google line chart from it. the idea is that data will continue coming and the chart has to be updated. What I'm doing right now is redraw the chart for every new data addition, which means redrawing the entire chart 20 times a second. This however slows down the process considerably.
What I'm wondering is, is there a way to add a row to Google Charts and take out a row (like shift and push) and have the chart update without redrawing?
If that doesn't work do you guys have suggestions for live data visualization tools?
Google charts are images served by Google's API. There's no way to change just part of an image, you have to load a new image. If you want a chart that changes, look at HighCharts. It's a Javascript charting package that has examples like you want. D3 also is very powerful, but requires more work.
