In certain models we need to be able to change the scale of the chart axes function of the result of a simulation. Excel charts do have auto-scaling as a default option but sometimes the scaling values we get are not what we need. Another reason against using auto-scaling is that during the time the model runs, the scale self-adjusts and… Read More... "Easy Zoom – Chart Axis Scaling Using VBA"
Hi there, this is a tutorial explaining the construction of a very basic Lissajous emulator in Excel. It’s supposed to be very easy to understand at the high school level. Good luck, George [sociallocker][/sociallocker] A Lissajous emulator in Excel by George Lungu Introduction: Jules A. Lissajous was a French mathematician from the 19th century – He wanted to visualize… Read More... "Tutorial – a Static Lissajous Emulator"
This is a dynamic Lissajous emulator in the sense that the waveform is obtained by combining 2 time varying sinusoidal waves with different frequencies. [sociallocker][/sociallocker] Read More... "Dynamic Lissajous Emulator"
This is a static Lissajous emulator in the sense that the waveform is obtained by combining 2 static sinusoidal waves with different frequencies. As a parenthesis, I will be preparing a dynamic version which will look just like the wave shape seen on a real oscilloscope. The file presented here has two different worksheets, the first one contains a classic 2D… Read More... "Static Lissajous Emulators (2D and 3D)"
