How to translate the title, axis labels and legend of a chart?

Question

I have successfully created a grouped bar chart using the Forena module. My application supports English, Portugese and Spanish.

But I am not able to translate my chart to Spanish and Portugese. I need to translate the chart title, labels on each axis and the legend.

Here is the chart I created so far:

I wonder how I can translate the following strings in this chart:

1. Biological and chemical indicators
2. Average of indicators
3. Positive biological indicators
4. non responsive chemical indicators

Answer 1

Here are the steps to create a translated version of a chart (or more general: a report) using the Forena module:

• Make sure (core) module locale is enabled.
• Instead of using the "edit" icon to change the specs of a report, use the "translate" button next to edit. Then select the language to which you want the report (chart) to be translated.
• On the next screen, enter the translated report (chart) title.

• You should get some informational message as in this example (in which I created a 'nl' version of drupaladmin/active_users, for which I changed the tite from "Active users" to "Actieve Gebruikers"):

  Translation, Actieve Gebruikers has been created. Switch languages to translate.

  Your report, nl/drupaladmin/active_users has been saved.

• After switching your active language to the language for which you want to create a translated version, you'll be able to change anything of the report (charts) specs to the specs of your additional language.

• In your case here, you can now modify those 4 strings

Bottomline: tranlating Forena reports is similar to translating nodes.
