retrieve the last plot region etc

[Yuandan Zhang]

Hi there 

I did a bit modification on LZ, adding a selection button to change between studies (datasets). Every time after the dataset changed, I want the LZ use the last view-region. How to retrieve the last plot status. 

regards

Yuandan

Greetings,

Thanks for the question. There are several versions of LocusZoom, and they don't all share the same code: can you clarify which version you are using? 

If you are asking for help with a specific piece of code, a github link can also be useful. (if the code is public)

fyi, 

i managed to make it work 

      const stateUrlMapping = {chr: "chrom", start: "start", end: "end"};

      initialState = LzDynamicUrls.paramsFromUrl(stateUrlMapping);

      if (!Object.keys(initialState).length) {

          initialState = {

              chr: CHR,

              start: REGION_MID - 250000,

              end: REGION_MID + 250000,

 

          };

      };

      plot.applyState({ state: initialState });
