title: Python PPTX - How to set chart axis number format and range
body: <p>I'm trying to accommodate a Bar Chart Y axis with a range from 0 to 1 with 1 decimal place like: 1.2 for tick labels:</p>
  
  <p>I can set it to start at 0 with:</p>
  
  <pre><code> Thisvalue_axis.minimum_scale = 0
  </code></pre>
  
  <p>And I can set the top value with:</p>
  
  <pre><code> Thisvalue_axis.major_unit = 1
  </code></pre>
  
  <p>But the intermediate tick labels are not showing</p>
  
  <p>here is my code:</p>
  
  <pre><code>Thisvalue_axis = ThisChart.value_axis
  Thisvalue_axis.minimum_scale = 0
  Thisvalue_axis.major_unit = 1
  Thisvalue_axis.minor_tick_mark = XL_TICK_MARK.OUTSIDE
  Thisvalue_axis.has_minor_gridlines = True
  </code></pre>
  
  <p>Is it possible to Make the values between 0 and 1 display and set the numberformat?</p>
