Data visualizer module feedback

Support - Assistance technique
1

Hi all,

now that you have had some time to get familiar with the new data
visualizer module we are interested in getting feedback and
suggestions for improvements based on real use-cases.

You can explore the module here:

http://apps.dhis2.org/demo/dhis-web-visualizer/app/index.html

So far through various channels we have received the following:

1. Integrated table of data listing what is currently displayed in the
chart (already implemented in trunk).

2. Saved chart views which can later be easily re-visited.

3. Export of chart views to PNG for download.

We encourage you to suggest new features accompanied with an
explanation why it will be useful for you.

best regards,

Lars

Hi Lars,

The data visualizer looks great. Would like to suggest the following:

  1. Please kindly remove the data visualizer from among the options for Start page under the Appearance settings page. This is because,

like we had in the past with the GIS module, the data visualiser loops back to itself and effectively locks the user out from being able to exit from the data visualizer once it is selected as the start page. You may try it and see.

  1. Ability to insert charts drawn in the data visualizer into the dashboard.

  2. Chart Title (and may be sub-title) for the data visualizer charts.

  3. The Chart Type buttons/icons on the top-left portion of the data visualizer window don’t seem to do anything. Would like to see the

Example chart change to reflect the user’s choice when any of the chart type icons is selected.

  1. The message in the information box eg. ‘No data values’, ‘Form is not complete’, that appears when one clicks the Update button

is too short (and cryptic). We should consider adding more details as to what the user should do to get the visualizer display the chart

depending on the circumstance.

These are the few that readily comes to mind. May add more as I take the data visualizer through much deeper tests.

Thank you so much to all the developers for making our lives easier with DHIS2.

John.

Yes, we are planning a new dashboard and this is the main reason.

  1. Chart Title (and may be sub-title) for the data visualizer charts.

The ExtJS chart engine does not offer a dedicated title option, but I just found a way to work around it so this will be available in trunk shortly. Currently, the chart title is simply displayed on the toolbar, next to the “update” button.

  1. The Chart Type buttons/icons on the top-left portion of the data visualizer window don’t seem to do anything. Would like to see the

Example chart change to reflect the user’s choice when any of the chart type icons is selected.

The visualizer is designed to be as network friendly as possible. That’s why the chart type buttons don’t execute anything (just think of them as a way to select the chart type). The chart is not updated unless the user specifically clicks the “update” button. Otherwise, if the user e.g. wants a different chart type and different indicators, and selects the chart type first, the chart is unnecessarily updated (and data transferred) twice.

  1. The message in the information box eg. ‘No data values’, ‘Form is not complete’, that appears when one clicks the Update button

is too short (and cryptic). We should consider adding more details as to what the user should do to get the visualizer display the chart

depending on the circumstance.

Improved notifications is already on the 2.6 roadmap. In trunk the “Form is not complete” is replaced by something a bit more informative, like “No indicators selected”, “No data elements selected” etc, but this will definitely be improved further.

These are the few that readily comes to mind. May add more as I take the data visualizer through much deeper tests.

Please feel free to provide feedback any time.

Hi Jan,

Some new requests from Kenya:

  1. Option to put values on the bars in the chart.

  2. Option to switch from colour scheme to a pattern scheme (e.g. dots, vertical lines, horizontal lines etc.) to distinguish between bars in a chart when printing in black&white mode.

  3. Would it be possible to combine indicator and data element into one object/option in the drop downs for Series, Category, Filter (top of the page)? This makes sense as you never do a chart with indicators as Category and data element as Filter or Series. Now the tool complains with “Form is not complete” if you select a few data elements and no indicators, and forget to switch from Indicator to Data Element on e.g. the Series. Seems unnecessary to force the user to do this switch.

  4. Generally the users are happy with this and really appreciate the possibility of creating and manipulating their own charts. And although screenshots are always possible they almost can’t wait to see the “save as image” button on the next release…

Good work, keep it up!

I was thinking that you would always show all selected data elements and indicators together on the same dimension/chart position.

Although I agree that it can be useful to quickly switch between already selected data elements and indicators, I think it will be even more useful to be able to show them both at the same time, especially now that we treat calculated data elements as indicators (many indicators are counts just like data elements).

Subject: [Dhis2-users] Data visualizer module feedback

Hi all,

now that you have had some time to get familiar with the new data
visualizer module we are interested in getting feedback and
suggestions for improvements based on real use-cases.

You can explore the module here:

http://apps.dhis2.org/demo/dhis-web-visualizer/app/index.html

So far through various channels we have received the following:

  1. Integrated table of data listing what is currently displayed in the
    chart (already implemented in trunk).

  2. Saved chart views which can later be easily re-visited.

  3. Export of chart views to PNG for download.

We encourage you to suggest new features accompanied with an
explanation why it will be useful for you.

best regards,

Lars

  1. Generally the users are happy with this and really appreciate the possibility of creating and manipulating their own charts. And although screenshots are always possible they almost can’t wait to see the “save as image” button on the next release…

This is now in trunk (png and pdf).
