As you say it's a great job by Rgraph, please congratulate them on my part. I have tried and it is very good.I have a problem with the following charts

1. A combined Scatter chart
2. A combined Scatter chart

I copy the code on the web, it gives errorError message:*** PHP-graph – invalid/missing parameter:-          “plugins/content/rgraph/doc/scatterdata.json  - File not found.I have checked on the web and the rgraph/doc folder does not exist. For this reason it cannot find the file.You can check and if you have those files send them to me, I am doing a job with scatter, I thank you for your prompt response.
