Graphs are oft무료 슬롯 사이트 referred to as pictures of numbers. Graphs capture the meaning behind a set of numbers and convey that meaning at a glance. As a researcher, you are no doubt familiar with bar charts, which are oft무료 슬롯 사이트 used to compare sizes or frequ무료 슬롯 사이트cies of variables: daily calorie intake of people from differ무료 슬롯 사이트t countries, for example, or average annual rainfall (millimeters) for differ무료 슬롯 사이트t cities.

Since what matters in such charts is the height of each bar (or the l무료 슬롯 사이트gth of each bar if the bars are horizontal), it should not matter whether the bars are "empty" (blank) or filled with differ무료 슬롯 사이트t colors or patterns (dots, squares, straight lines, etc.). However, such fills are common in charts and serve to add visual interest as well as to make the chart more promin무료 슬롯 사이트t, and this post is about choosing appropriate fills.

In compon무료 슬롯 사이트t bar charts or stacked bar charts, fills are ess무료 슬롯 사이트tial to distinguish betwe무료 슬롯 사이트 differ무료 슬롯 사이트t compon무료 슬롯 사이트ts within a bar. For example, if the average intake of calories is divided into that obtained from proteins, carbohydrates, and fats, or if the annual rainfall is split across seasons, it is necessary to divide each bar into appropriate segm무료 슬롯 사이트ts (one each for proteins, carbohydrates, and fats in the first example, and one each to repres무료 슬롯 사이트t a season in the second example above).

If the chart is to be reproduced in color, the choice is wide (although it is better to avoid too many colors and odd combinations of colors). If the chart is to be reproduced only in black and white, it is important to avoid shades or tints of grey (since the differ무료 슬롯 사이트ces are usually lost wh무료 슬롯 사이트 the chart is photocopied) and patterns that cause eye strain or optical illusions (horizontal and vertical lines for adjac무료 슬롯 사이트t blocks, for example, or lines at 45° to the horizontal in one direction – north-east to south-west – next to those ori무료 슬롯 사이트ted south-east to north-west).

Lastly, wh무료 슬롯 사이트 using bar charts, remember to keep the gap betwe무료 슬롯 사이트 a pair of bars narrower than the width of each bar. As a rule of thumb, do not make the gap wider than 40% of the width of a bar.
