So basically I have been working with some code to try and use a checkbox to hide/show a graph, the big issue is that the graph is made using dygraph and the graphs are made from a csv file's data therefore there is no specific line of code that the graph corresponds with. I am basically stuck because I really don't know how to get around this problem. I can go in to the website once the data is inputed and show/hide the graph that way however different file will have different amounts of data so I can't just do that every time.
When you create the graph, you specify a div that the graph should be drawn in. Can't you simply show/hide that div?
I used this tutorial to display an yahoo chart with d3js http://bl.ocks.org/ColinEberhardt/c806028e47281b8dbb1d
now i would like to make it as Real Time chart,and i would like some help to add data every 10 seconds for example.
Thanks
PS : I am using d3js and d3fc, and i don't use path
I am working on Highcharts and want to use real data e.g weather for a particular city. I would want to plot it in a basic line graph. I am new to using highcharts so please bear with me.
I am using HighChart library for creating charts in my web application in ASP .Net.
First i use this Candlestick chart for showing the company's stock on chart.
Now i want to create chart for forecast data (RSI CFM Typical Price Moving Average) values on chart.
I see the following picture somewhere but i don't have its example or demo.
Is there any working example for that?
It looks like scenario where indicator are calculated as additonal series. Check the plugins registry, where some of them are implemented.

I'm outputting a line graph to my page using the Highcharts API and applying the following methods to it:
zoomType: 'x',
event.preventDefault(),
alert(event.xAxis.min) & alert(event.xAxis.max)
This gives the user the ability to highlight a portion of the chart, and have it output the start time and the end time they highlighted without zooming in.
This works great but now I need to literally highlight that section of the graph the user selected. I've been having a look at the xAxis.plotBands method detailed here:
http://api.highcharts.com/highcharts#xAxis.plotBands
xAxis.plotBands allows me to hard code a highlight into the chart but I'm trying to figure out if it's possible to apply plot bands on the fly. It's important that the chart doesn't reset because the user can dynamically add series to the chart as well, so if it resets, the user loses all the series they added. Anyone know if it's possible?
Yes, this can be done with xAxis[i].addPlotBand().
