The Timeline feature allows you to explore the elements of the set time period. This is great for getting a feel for how the PSE evolved over time, as more and more elements were discovered. You can active this feature via Miscellaneous->Show/Hide Timeline or by clicking the Clock icon on the toolbar. If it is activated you will see a slider below the PSE and an LCD which displays the number 2004. If you move the slider you will notice that some elements disappear if you move it to the right and reappear if you move it to the right. Furthermore the number will change constantly.
The number represents the date you are looking at. If you move the slider to e.g. 1856 you will only see the elements which where known in the year 1856.
You will notice that some elements are not even shown in the year 2004. This is because some of the elements have not been discovered yet but are predicted to exist.
After you hide the Timeline, the display will stay at the year you choose and if closed, Kalzium will restore that date at next run.

The Plot Data dialog allows you to plot some information about elements. The X-axis represents a range of elements (from one number to a higher number). You set this range using the First Element and Last Element fields on the dialog.
Kalzium can plot some data about a range of elements.
With the Show/Hide State Of Matter: you can choose which state you want depending of the temperature. You can easily visualize how many elements and what elements are for example solid at a given temperature. So you can learn that almost all are solid at very low temperatures and that most are liquid or even vaporous at high temperatures.
Kalzium can show you which elements are solid/liquid/vaporous at a given temperature.
