What label you want to add in special?
At http://dev.sencha.com/deploy/dev/docs/
navigate to ext, charts, there you see "labelFunction" which you can use to add your labels.
create text sprites for the title or any labels.
Look at the Ex.draw package.

I want to clarify very clearly in a Data Studio report what the date range is that the report is currently running over.
So I want to add a text box up at the top of the screen to display this.
Is this possible?
From what I understand text labels can't display anything dynamically. Is it possible to do this with a function using the 'scorecard' data chart type or something similar ?
No, you can't make a label dynamic. However, you can make a table look like a label.
If you remove everything from a table (row numbers, title, border, colors, etc) it will look like a label with the ability to update dynamically. You can also use this trick to display dynamic images.
After this, just add any date field you already have as a metric, using functions MIN or MAX accordingly.
Step-by-step to turn a table into a dynamic label:
Disable Show header
Cell table color: Transparent
Odd/Even row color: Transparent
Disable Row numbers
Disable Show pagination
Background color: Transparent
Border color: Transparent
Chart header: Do not show
I made a public dashboard to illustrate the results:

I am using React + Recharts to create a stacked bar chart, is it possible to make data label look like the below image?

You can just add another rect, working sample: https://codesandbox.io/s/rechartsstackedverticalbarchart-test-forked-433bb?file=/src/App.js:554-631
I have created bar chart using Google data studio. Now I have to add a dimension values(For each BookingCategory in chart we have different agents. So I want to display Agents with there booking count in each bar Tooltip) on the tooltip of the barchart.
Is this Feasible to achieve ?
You can show bookings by agent in your bar chart by adding it as a secondary/breakdown dimensions and selected "stacked" in the style menu.
Hopefully I've understood your question correctly!
Hello how can I remove a series from a chart, I know that I can get the series object using getAt(0) or getAt(1) depending on how many serieses I got in my chart.
my question is how can I remove a series from the chart.
main reason is that I give the end user the ability to change the series type: bar, line... so I wan to display the new change at run time by removing the series and adding a new one.
I tried Chart.series.removeAt(0); It removes the legend but the bar or the line still shown !!
I use extjs 4.1.1
thank you,
I had to do the same thing and give end users the ability to change the chart type at run time to give different visualizations of data. I found that there is more involved in the chart type (bar, line, pie) then just the series. In other words to achieve this, I wasn't able to just substitute a different series type for the data and add it to the chart.
I ended up creating a different config for each different type of chart using the same datastore. The chart was contained by an Ext.panel.Panel which I added this function to:
// toggle format between pie chart and bar chart
this.toggleFormat = function() {
var chart = me.down('chart');
this.remove(chart);
if (chart.chartType == 'pie') {
this.add(Ext.create('Ext.chart.Chart', bar));
} else {
this.add(Ext.create('Ext.chart.Chart', pie));
}
};
The bar variable holds a bar chart config and pie holds a pie chart config but both had the same datastore attached to their store: configs.
When the user pressed the format button I called this function to remove the chart from the panel and create one with the different format. It achieved the desired effect.
I am using ExtJS for GUI. I want to plot a line chart inside a Grid Panel. Is this possible? If so, how do we do this?

An idea:
Define a custom renderer function (set a renderer on the column definition).
In the renderer, generate markup for an iframe that references the Google Charts API.
(I'm not familiar with Ext charts - you'd probably want to end up with those ...)
