Correlation matrix with Highchart heatmap (hchart.matrix) #86

Closed adymimos closed 8 years ago

adymimos commented 8 years ago

It would be great if you can add a function which gives correlation matrix with highchart heatmap. Is it possible to create one?

@adymimos

Obviously this is possible :wink:. I'll put this on the enhancement tag. If you have a mockup code to start from there is very welcome if not the case I'll take some time the next week. I think this wont be hard, we need to reuse https://github.com/jbkunst/highcharter/blob/master/R/hchart.R#L220

I have an implementation highcharts with rCharts. But it is not as good as one with polycharts [http://rcharts.io/viewer/?7073094#.VyAiXrO_vEU]. With highchart color gradient always screws up. Let me try to make an example with dist

@jbkunst Thanks for the pointer. I was able to implement it.

pls let me know if you require this as a new function, I can create a pull request

Nice @adymimos :smile: !

Mmm not sure how include this function becuase class(cor(mtcars)) is matrix. Maybe is a good/reasonable alternative if we make heatmaps to chart matrix in the hchart function by default.

Can you make a pull request modifying hchart.R file and creating hchart.matrix(object, ...) function with your code? Are you agree? If you do, modify DESCRIPTION file adding you name as ctb.

Thanks and regards,

In my browser the "-1" in the legend is cut off. Is there anyway to pad it so the -1 doesn't get cut off?

Hi @jrounds ,

Sorry for the late reponse.

I think the issue is caused by some options given by @adymimos in the hchart.matrix in the legend option, I removed them so highcharter will use the default ones.

Thanks!
