the combo chart is suitable for
comparing two sets of measure values
that are usually hard to compare because
of the differences in scale
A typical example is when you have a bar chart with sales figures
and want to combine these figures with the margin values in percent
with a combo chart you can combine these values by, for example:
using bars for the sales values
 and a line for the margin values
by default,  the bars have the measure axis on the left
and the margin values have a separate access to the right
while the two measures use the same dimension
in this case, product group
if you have yet another measure with values that are roughly in the same range as the sales values
you can add the third measure as bars and either stack or group the new measure values with the sales values
with grouped bars you can easily compare two or more items in the same categorical group
stacked bars combine bars 
of different groups on top of each other
and the total height of the resulting bar represents the combined result
to create a combo chart, drag-and-drop
the combo chart onto your sheet
add a dimension, for example product group
then add a measure, for example sales quantity
then add a second measure 
for example margin percentage
this will create a combo chart showing the product group and the sales quantity as bars
and the margin percentage as a line
you can't format your combo chart in different ways
In this example, we are going to create a new chart with region name as dimension
then we add three measures to
the chart
you can only have one dimension 
but you can continue adding up to 15 measures
when finished 
we can change the appearance of the chart
for example 
you can show the sales target measure as a marker
and you can do the same for the sales cost amount
to differentiate it from the previous marker 
you can show this as a line
in this example ,we add customer as
dimension and total shipment as a measure
then you can exclude null values and you
can limit the number of values to the top 15
then you can compare the total shipment
with the other two values
in this case, the on-time shipments and the late shipments
when done, you can select bars for both
measures
this way you can see the ratio between on-time and late shipments at a glance
bars can be showed grouped or stacked
by selecting stacked you can't see the combined result of different groups
displayed by the total height of the bar
and that concludes this video, thanks for
watching!
