I’ve created a line chart with records group by year, but the output is showing extra X-axis values that don’t exist. For example, my data has years 2017, 2018, 2019, and 2020, but the x axis of the chart is adding interim values of 2017.5 between 2017 and 2018, 2018.5 between 2018 and 2019, etc. How can I suppress this output? It looks very unprofessional.
