About this course
Manish Gupta and TA eHMS start with a question that matters more than the chart menu: what should the viewer understand? Data types, comparisons, relationships and trends are considered before the course examines particular Excel charts and their limits.
The teaching combines design principles with short demonstrations. Bar and column charts receive a longer practice segment, while later lessons introduce area, line, histogram, scatter, treemap and waterfall displays. Good and misleading examples help explain why a technically correct chart can still communicate poorly.

Although the original title says under one hour, the listed duration is 64 minutes across 22 lectures and two sections. Basic Excel knowledge is expected. Several chart types receive only a minute or two; this is an orientation to selection and presentation, not an exhaustive course in every chart feature.
Some examples use ordinary business figures or stock prices to illustrate chart behavior; the visible syllabus does not teach trading strategies. Desktop Excel may require a licence. Basic comparison and trend charts can also be explored in a free spreadsheet such as LibreOffice Calc, although menus and newer Excel chart types will not match exactly.
Frequently asked questions
Is the entire course under sixty minutes?
The source reports 64 minutes; the article uses that duration instead of repeating the shorter title claim.
Will every chart receive a full project?
No. The syllabus mixes brief explanations with a longer bar-chart practice segment.
