Zoo,lable Chart - DATE on the x axis - VERY VERY slow

[swman]

Dear Support.

we use
- problem Zoom able time charts are very slow
- GWT Pro 4.0d - 13.4.2013
- Tested with IE und firefox
- showcase example attached: yes!


Attached you find a show case sample TimeDataZoom, that shows the problem.

In opposite to the MeasurementDataZoom example it we fill a DATE in the x-axis.

when we load len=100 record in getData
=> the curve comes after a view seconds,
when we load len=200 record in getData
=> the curve comes after > 30 secons
when we load len=1000 record in getData
=> it takes forever


When you do the same test with the MeasurementDataZoom shwocase example and modify the len variable in the getData mehode, it is always acceptable fast!

For me this shows:
- There is a problem with zoombale charts in combination with DATE on the x-axis.


In my oppinion zoomable charts shall be used to show a lot of data with the possiblity to zoom in.

I would expect to show at least 10000 records fast!

Thank you for the feedback and fix.

You can verify this problem easily by running the showcase!

See the FAQ for common reasons for slowness, and please verify that you've checked all of those possible causes (list results for each).

slow chart

Dear Support,

you get m wrong.

Example one is fast enough - this is your orginal showcase.

I just just a Data instead of a number on a the x axis - The showcase code is uploaded! This case is very slow.

Please! understand that if one exeample is fast and the other is very slow with 99,5% the same code , the a developer has to check the rendering of Date values!

I dont send this ticket to waste our and your time, I would like to have a fast zoom able chart with date/time on the x-axis.

This is a common case and should work!

[Isomorphic]

You need to actually read the FAQ. You haven't even indicated if you're running in the development mode or not, step #1 in the FAQ.

[swman]

it was tested in the hosted mode!

is there anything else you need what is not addded yet?

I have developed a extra showcase sample, what can I don more to convince you that this is problem?

The developer can run it in one minute and will see that this is not working.

This is the second case where I run agains wall

[Isomorphic]

So, as the FAQ says, don't test performance in hosted/development mode. It's 10-1000x slower and can show apparent performance problems that won't really exist in your deployed application, because they are introduced by GWT's special development mode behaviors.

[swman]

it is the same in the production mode!

Ask the developers to run this sample!


Why isomorphic does everything and invest as much time as possible to get away of bugs, instead of fixing them?


WE HAVE BOUGHT YOUr SOFTWARE BECAUSE OF ZOOMABLE CHARTS AND NOT ITS NOT WORKING. I WILL COMPLAIN!

[Isomorphic]

Why isomorphic does everything and invest as much time as possible to get away of bugs, instead of fixing them?

As is blindingly obvious to people following the forum, the exact opposite is true - we encourage users to read the docs and read the FAQ so that we do not waste time on false bug reports.

Every time there is a false bug report and we investigate and find that there is no problem, some other, real bug report is not looked at and the bug not fixed.

So next time just follow directions the first time, without being asked twice, and we will be able to immediately look into a possible bug instead of wasting your time and ours.

solved

Dear Support,

you can close this ticket!

I guess it was my mistake. The production mode after a full recompile and tetest showed the zoom able chart with date columns in with 1500 records in ~5 seconds, what is OK!

Thank you
