Use Entrance PLOT to make charts.

PLOT AXISLABELS, RED LINE SELECT year, average

FROM cpi WHERE year >= 1960 AND year < 2007;

Essentially any MySQL SELECT statement works.

PLOT AXISLABELS, RED LINE SELECT year, average

FROM cpi WHERE year >= 1960

AND year < 2007;

Chart setup is simple.

PLOT AXISLABELS, RED LINE

SELECT year, average FROM cpi

WHERE year >= 1960 AND year < 2007;

Just be sure the chart series match up1-to-1 with result set columns.

PLOT AXISLABELS, RED LINE SELECT year, average

FROM cpi WHERE year >= 1960 AND year < 2007;

. . . and the script that made them:

An Entrance EarthChart . . .

PLOT EARTHCHART X, VERY SMALL FILLED YELLOW CIRCLESELECT LON, LAT FROM ACCESS_LOCIDS;

. . . and the script that made it:

Entrance Rotated Bars . . .

. . . and how to make them:

Entrance supports named colors.

See http://dbentrance.com/blog/for more examples.

(A good one: search for “Benson”)

PLOT scripts can also be run from the command line or EntranceServlet.

(The servlet makes us cloud friendly)

Use Entrance to makesimple, clear data graphics.

(No 2.5D, no chart junk)

Use Entrance + MySQLto perform data analysis.

PLOT AXISLABELS, SKYBLUE LINE, DATALABELS ABOVE, DATALABELS BELOW WITH PAGE HALF FONT "sanserif" plain 13 TITLE CENTER "Monthly Average Stock Prices, 1928-1932" NO SIDES NO YAXIS NO XAXIS COLLARSELECT b.date,b.p, IF(b.p > a.p and b.p > c.p, b.date, ''), IF(b.p < a.p and b.p < c.p, b.date, '') FROM price_earnings a, price_earnings b, price_earnings c where b.date > 1928 and b.date < 1933 and a.rownumbers = b.rownumbers - 1 and b.rownumbers = c.rownumbers - 1 ;

This script “tags” inflection points.

Tagging data items.

... to make plots like these:

PLOT VERY THICK SKYBLUE LINE, COLOR OVERRIDE NO YAXIS NO XAXIS NO SIDESSELECT jan, IF(year >= 1960 and year <= 1980, 'red', '') FROM CPI where year >= 1920 ;

This script uses a COLOR OVERRIDE:

. . . to highlight a section of a line:

 name                  who               --------------------  --------------    Alabama               strong mccain     Alaska                strong mccain     Arizona               strong mccain     Arkansas              strong mccain     California            strong obama      Colorado              strong obama      Connecticut           strong obama      Delaware              strong obama     

...

Scripting the Red-Blue States:

PLOT USColoringBook LAYER, COLOR OVERRIDE WITH -- maintain the frame aspect ratio 500:375 PAGE 0 0 500 375 BACKGROUND gray FOREGROUND white SELECT name, CONCAT( if(who LIKE 'leaning%', 'light', ''), ' ', if(who LIKE '%mccain', 'red', 'blue')) FROM election_projection WHERE who NOT LIKE 'tossup'UNIONSELECT name, 'very light yellow' FROM election_projection WHERE who LIKE 'tossup'UNIONSELECT "states_outline", "white";

Use a COLOR OVERRIDE:

. . . to make the “Red Blue States” map:

PLOT MAPCHART -- MapQuest API RED CIRCLE, LON, DATALABELS LEFT WITH MAP CENTER 37.14421218525334 -122.1341232266594 MAP SCALE 350000SELECT 37.14421218525334, -122.1341232266594, "OUR HOUSE";

The basic system can be extended:

... for custom applications:

And now, the live demo.

Requirements

Entrance is cross platform.

It requires Java JRE 1.5 or greater + access to a MySQL server.

* There are ways to use Entrance with other JDBC databases, too.

Access to the MySQL server isa problem with some ISPs.

Install a local copy of MySQL and download data in those cases.

(You can also tunnel if SSH is available)

Use Entrance Tools | Import to loaddata into a local copy of MySQL.

Entrance Import can import datadirectly from the web, eg. we use

it to import PHP script output.

Use Edit | Paste as table... to paste clipboard data into

a local copy of MySQL

Door.
