Google Combo Chart配置：堆叠柱形+折线图实现方案咨询

Hey there! I’ve helped plenty of folks troubleshoot this exact combo chart setup, so let’s get yours working perfectly—stacked bars for Percent and Overtime, with a fixed line for Target. Here’s a step-by-step guide tailored to your sheet:

Step 1: Confirm Your Data Layout #

First, double-check your data is organized correctly (I’m assuming your sheet has:

• A category column (e.g., dates, project names) in the first column
• Percent in the second column, Overtime in the third, Target in the fourth
• All headers are included at the top of each column

If your layout is different, just adjust the steps below to match your column order.

Step 2: Insert the Combo Chart #

1. Select all your data (including headers—drag from the first cell of your category column to the last row of your data)
2. Go to the top menu: Insert > Chart
3. The default chart might not be a combo chart, so in the right-side Chart editor, go to the Setup tab and set Chart type to Combo chart

Step 3: Configure the Series (The Critical Part!) #

This is where most people get stuck—let’s nail the series settings to get stacking and the line right:

1. Switch to the Customize tab in the Chart editor
2. Scroll down to the Series section:
   • Find the Percent series in the dropdown:
     • Set Type to Bar
     • Check the box for Stacked (you’ll see this option when you expand the series details)
   • Next, select the Overtime series:
     • Set Type to Bar
     • Also check Stacked—now these two bars will stack on top of each other for every category
   • Finally, select the Target series:
     • Set Type to Line
     • Optional: Tweak the line color or thickness here to make it stand out against the bars
3. Adjust the Axes (if needed):
   • Go to Axes > Left vertical axis
   • If your Percent and Target are percentages, set Format to Percent to match your data
   • Adjust the Min and Max values if your line or bars are getting cut off—this ensures all your data fits neatly

Common Pitfalls to Avoid #

• Don’t assign Target to a separate right axis unless its values are drastically different from Percent/Overtime—this will break the alignment of the line with the bars
• Make sure only the bar series have Stacked checked—leaving this on for the line series will cause weird behavior
• If stacking still isn’t working, go back to the Setup tab and confirm your data range includes all three metric columns and no extra rows/columns

Once you tweak these settings, your chart should show stacked bars for Percent and Overtime, with a clean line tracking your Target values across each category.
