Hard-coding the scaling of how values are visually represented is not advisable since we'll often plot charts from very large databases. You can improve your code from the previous video to tackle this.
- [Instructor] Previously, we saw how to add a legend…to the charts.…In this video, we'll scale our charts.…We'll increase one value in the data…and see the effect on our chart.…After that, we'll set limits to the chart…and see what changes.…In the previous videos, while creating our first charts…and enhancing them, we hard coated the scaling…of how those values are visually represented.…While this served us well for the values we were using…we often plot charts from very large databases.…
Depending on the range of that data our hard coated values…for the vertical, wide dimension might not…always be the best solution, which may make it hard…to see the lines in our charts.…Here, we will improve our code from the previous video.…Now, we will modify the values.…Y values one, from the previous video to use 50…as the third value.…We'll also remove the colors which we specified.…The only difference to the code that created the chart…in the previous video is one data value.…
Let's see how the output gets effected by this.…
