Display a Excel chart in Html page - javascript

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.

Bokeh export all charts, tables in a single image

I m building some chart usign bokeh chart.
This is the output:
Now I want to know if is possible to create a Print or an image to print. In my case I can export as image only chart and not Table too.
AFAIK, there's nothing built into Bokeh for that.
However, you can implement it directly using some of the links in this answer: https://stackoverflow.com/a/18581496/564509
Alternatively, you can just print the whole web page using window.print().

Google Data Studio custom charts

I need to use a Google Data Studio pivot table with conditional formatting, what it doesn't support out-of-the-box, hence I'm trying to code a custom table that does it. I reached this tutorial, but can't find any documentation about how to change a bar chart to a table.
Custom charts (Community Visualizations) are created using JavaScript. If you want to create your own table/pivot table viz, you will need to write JavaScript code for that. For example, you can use the Google Charts library to render tables.

html page getting hanged with to many d3.js radar chart

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.

read input from text file for data in google chart api

I am using the Google Chart API to implement a pie chart.The example on their website: https://code.google.com/apis/ajax/playground/?type=visualization#pie_chart uses static values to make the chart.
What if I want the data to be read from a text file? How do I go about doing it?

Scrolling in jqPlot

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:
http://screencast.com/t/mHY5eUV99XaT
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.
