      Insert excerpt
      _app_mode
      _app_mode
      nopaneltrue
       to see the chart.

Setting an upper limit

There is one data point in the data which is much greater than all the others, so movements in the levels of debt cannot be seen.

...

We can exclude this outlier and generate a more useful graph.

...

  1. Switch back to
    Insert excerpt
    _design_mode
    _design_mode
    nopaneltrue
     and
    Insert excerpt
    _view_show
    _view_show
    nopaneltrue
     configuration
  2. In the Chart Layout section, add a Maximum Value to the Vertical Axis of 30000

Then view the chart to see the results.

Setting a lower limit

You decide you are only interested if there is a debt level of more than 5,000.

  1. Under Vertical Axis, set Minimum Value to 5000

...

Then view the chart to see the results.

Fixing the scale

You now decide that you want to show the graph always including the Vertical Axis (Y

...

) starting at zero:

...

  1. Under Vertical Axis, set the Minimum Value to 0

...

  1. Fixed Scale
    Insert excerpt
    _toggle_on
    _toggle_on
    nopaneltrue

Then view the chart to see the results.
Note: Fixed Scale is relevant when the graph data changes. The Minimum Value and Maximum will always be plotted on the Vertical Axis (Y

...

), even when the largest data value is lower than the Maximum Value and the lowest data value is larger than the Minimum Value.

Create a

...

bar chart

Now you will create a graph of the same data, but this time using a bar chart.

  1. Create a

...

  1. screen called Debt levels by payment means 2

...

  1. Select a Template e.g. Tile No Buttons.
  2. Now create a new view on the screen.
  3. From the screen's toolbar, click
    Insert excerpt

     the settings.

  2. Go into

    Insert excerpt
    _app_mode
    _app_mode
    nopaneltrue
     to view the results.

The view looks very cluttered – but we will filter this later to make this more useful.

Create an aggregate grid view

Now you will create a grid view on the data in Overall Debt Levels, but to show aggregated totals by payment method:

  1. Create a

...

  1. screen called Debt totals by payment means.
  2. Select a Template e.g. Tile No Buttons.
  3. From the screen's toolbar, click
    Insert excerpt
    _tableOnly

...

  1. _tableOnly
    nopaneltrue
    s.
  2. Drag the table Overall debt levels onto the

...

  1. screen.
  2. Select the view type

...

  1. Insert excerpt
    _grid
    _grid
    nopaneltrue
    .
  2. Drag the following attributes onto the

...

  1. view

...

  1. :
    • PaymentMeans
    • DebtLevel
    • Count()
  2. We want to group the results by PaymentMeans, and for each value of this, sum the DebtLevel:

    ...

      1. Right-click on the grid and select
        Insert excerpt
        _view_show
        _view_show
        nopaneltrue
         configuration
      2. Update the Name of the view to Debt totals by payment means
      3. Double

    ...

      1. -click on

    ...

      1. DebtLevel in the View Attributes list

    ...

      1. :
        • Set the Name to TotalDebtLevel
        • Select the

    ...

        • Aggregate Function: Sum
        • Press 

    ...

        • Insert excerpt
          _finish
          _finish
          nopaneltrue
          .
    1. Press 
      Insert excerpt
      _finish
      _finish
      nopaneltrue
       on the View settings to save your changes.

    You should now see an aggregate view with an entry per Payment Means - 3 rows in total - with, for each, a sum of entries for that Payment Means, and a total debt level.

    Create a

    ...

    pie chart

    Now you will create a further chart on the

    ...

    table Overall Debt Levels, to give an overview of proportions of debt by various payment means. Create a new

    ...

    screen and view with the settings:

    Debt overview by payment means
