Before we started to do real on Excel charts it is important to understand what our charts and why we
invest our time and other resources on creating them what additional value we are generating by converting
our data in the form of charts so let's start with the basics chart is a visual representation of numerical
data.
It can make your numbers more understandable charts represent our data in the form of pictures which
often helps us to support trends and patterns that otherwise go unnoticed.
Let's look at an example to understand this.
Here we have monthly sales data of a company and let us see and try to identify the pattern in this
data so you can look at this numerical data.
I'll give you 10 seconds to analyze this and identify the pattern.
I hope you have identified deeper than no let's look at the chart of sales of another company and try
to identify.
But then again you have trends against
I hope you have noticed the difference between the two scenarios and I am sure that you would not need
10 seconds to identify the pattern in the second chart in case of Company B.
You can easily interpret that the sales are higher in the middle months of the year whereas you need
much more time in interpreting the same result for Company A If we had millions of values instead of
just drill it would be almost impossible for us to interpret these hidden patterns by just looking at
these numerical values charts become more and more important as these days of data increases so with
this backdrop in the next video we will be learning how to convey a message using a chart.
