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?

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.
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

You need to get json, call point.update and chart will be redrawn.
Any one know how to create PIE chart for data from db [table] using pure JS.
There are some tools like google chart, Rgraph and other. But I dont want any external calls. So anyone has any idea about creating independant pie chart?
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.
